Robin and I googled this person who was on the package of this cake. He was an emperor in old time, and he loved tea so much that he neglected his country. But this cake saved china later. China started to spread the rumor about this cake could cure plague. After moon cakes became popular, Chinese hid the message in this cake to exchange information. This idea worked . Soon, Mongolian retreated and Chinese empire restored. Interesting! 4000 years of Chinese history…, oh wait, is it 5000 years?
